1365	bitwise-not returns wrong values on non-negative arguments	johnwcowan		The expression {{{(bitwise-not 0)}}} returns 4611686018427387903 (i.e. 0x3fffffffffffffff) instead of -1.  The {{{fxnot}}} procedure does not have this problem, nor does the numbers-egg version of {{{bitwise-not}}}.  However, {{{(bitwise-not -1)}}} correctly returns 0.	defect	closed	minor	5.1	core libraries	4.12.0	wontfix			trivial
